Hyaluronic acid filler
Hyaluronic acid gel is injected to fill areas such as smile lines (the folds running from nose to mouth) and hollow cheeks, for a temporary improvement.
Depth: dermis to subcutaneous fat This is a model, so layer thickness is not to scale.
How it works
Examination firstWhere hollowness comes from sagging, a lifting treatment may suit you better than filler. We first examine which layer the change is in.
01What it uses
Hyaluronic acid gel
A gel form of hyaluronic acid, a substance already found in skin. It can be dissolved with an enzyme called hyaluronidase.
02Which layer
Dermis to subcutaneous fat
Lines are filled in the dermis, and hollow cheeks in the subcutaneous fat. Blood vessels run through these layers, so we inject away from where they lie.
03How it works
Filling hollow areas
The gel adds volume and softens shadows. As the body slowly absorbs it, the volume gradually decreases.
Concerns and how it works
If this sounds like you
- My smile lines look deep
- Hollow cheeks make me look tired
- Hollows around my mouth cast shadows
Over time, the face loses volume in its fat and around the bone, and shadows appear. Filler places hyaluronic acid gel in the dermis or subcutaneous fat to fill the hollow areas. It usually lasts 6–12 months. Because of a rare complication in which a blood vessel becomes blocked, we choose where and how deep to inject with great care.

What it is for
Temporary improvement of areas such as smile lines and hollow cheeks. How much your skin changes, and how quickly, varies from person to person.
Side effects
Swelling, bruising, lumpiness, and, rarely, inflammation can occur. Very rarely, a blocked blood vessel can lead to skin necrosis (tissue death) and, between the brows or around the nose, to reduced vision or blindness. If your skin turns white or dark red, or your vision becomes blurry after treatment, contact us right away.
Blocked blood vesselsVery rarely, filler can block a blood vessel. This can cause skin necrosis (tissue death) and, between the brows or around the nose, reduced vision or blindness. After treatment, if your skin turns white or dark red, or your vision becomes blurry, contact us right away. If a blocked vessel is suspected, we use the dissolving enzyme (hyaluronidase) immediately.

Common questions
What people often ask about hyaluronic acid filler
How much pain should I expect?
We apply numbing cream and use a local anesthetic if needed. You will feel a sting and some pressure as the needle goes in, and the sensation differs from person to person. The treatment takes 15–30 minutes.
How long will it take me to recover?
Redness, swelling, and bruising usually settle within 1–2 weeks. During that time, the area may feel lumpy to the touch.
How many sessions will I need?
One session, which usually lasts 6–12 months. Once it has been absorbed, we look at your skin again and decide whether to add more.
Can I combine it with other treatments?
Botulinum toxin is sometimes given on the same day. If you also plan a lifting treatment, we set the order and spacing after an examination.
